I’m trying to write some really basic UI tests with dev07's test library (findByText and friends), but even really simple assertions fail unexpectedly. Are there any limitations around what the semantics/testing infra can handle? More in thread.

This test, for example, tries to just assert some static text is displayed, to verify the app launched, but if you uncomment the commented line, it fails: https://github.com/zach-klippenstein/compose-backstack/blob/master/sample/src/androidTest/java/com/zachklipp/compose/backstack/sample/SampleAppTest.kt#L20-L23

I looked at the tests for Compose (on cs.android.com), and the most notable difference is that this one is testing a custom activity, so it’s using AndroidComposeTestRule instead of createComposeRule. However, I also tried writing tests without using a custom activity, and while the simplest one works, most of them also fail on basic assertions: https://github.com/zach-klippenstein/compose-backstack/blob/master/backstack/src/androidTest/java/com/zachklipp/compose/backstack/BackstackTest.kt
